INCUBATOR.

Application filed October 26, 1922. Seria1`No. 596,978.

'To all 'whom t may concern.'

which the following is a specification.

provements in incubators.

The present invention is directed to im The primary object of the invention is to provide an incubator having a cooling compartment between the incubation chambers, said compartment being so arranged that the egg trays can be removed from the incubation chambers at certain intervals and placed in the cooling compartment for a predetermined period to aid in the process of incubation. It is a well known fact that during the process of incubation it is necessary to cool the eggs at intervals, and heretofore it was necessary after removing the egg containing trays from the respective incubation chambers to place them on tables or the like, which not only consumed time but was extremely inconvenient, and owing to the unnecessary handling detrimental, and it is to overcome these objections that the present invention has been perfected.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a front view of the incubator, and

Figure 2 is a sectional view on the line 2 2 of Figure 1.

Referring to the drawing, 1 designates the incubator which consists of upper and lower incubation chambers 2 and 3, respectively. said chambers being held rigidly spaced in vertical relationship by end sections 4` said sections having their lower ends provided with legs 5 which serve to support the incubator. By this construction a compartment 6 is provided between the chambers 2 and 3, the ends 4 constituting closures for the ends of said compartment, while both sides of said compartment are open. This compartment has located therein a plurality of vertical posts 7 which are disposed adjacent the open sides of the compartment and have their upper and lower ends fixed to the ychambers 2 and 3re spectively. These posts serve to support the transverse partitions 8 and floor 9, the latter dividing the. compartment into upper ier..

and lower tray receivingchambers 10 andv 11 respectively. It will be observed that the partitions 8 are of such height as to not contact with the bottom and top of the chambers 2 and 3, thereby providing permit the free circulation of air.

rThe partitions 8 have fixed on their op-i posite sides tray guides 12, similar guides 13 i being associated with the inner face of the ends 4, said guides serving to slidably receive the legg trays 14 when removed from their respective chambers 2 and 3.

It will beapparent that the trays 12 when removed from the incubation chamber 2'wi1l be placed in the upper chamber 10, while the trays from the chamber 3 will be placed in the chamber 11 when it is desired to eggs in saidtrays.

The chambers 2 and 3 have associated therewith independent heating units 15 of any well known construction and it will be further observed that by providing the compartment 6 that heat from the lower chamber 3 will be prevented from heating the chamberv 2, as would occur shouldthe chambers be in mutual contact.

It is ar well known fact that certain space y to cool the fumes arise from incubationv chambers and ceiving chambers for receiving the egg trayA when removed from their respective incubation chambers.

3. An incubator comprising upper and 5 lower incubation chambers for containing egg trays, seid chambers being vertically spaced to provide an open sided compartnient, transverse partitions mounted in the compartment, a Hoor dividing the compartment into upper and lower tray receiving chzn'i'ibers for slidably receiving the egg trays from the respective incubation chambers.

In testimony whereof' l Linx my signature.
